Title: Sputtering process
IPC: H01L23/522
Filed: 1971-11-22
Abstract: 1361214 Sputter etching INTERNATIONAL BUSINESS MACHINES CORP 22 Nov 1971 [31 Dec 1970] 54058/71 Heading C7F A thin film device comprises a substrate 56, a metal stripe 54 and a sputtered passivating insulating film of SiO 2 , 52. To achieve a planar upper surface of the SiO 2  film 52, sputter etching is carried out by positive ion bombardment of the SiO 2  film. The sputtering and sputter-etching operations may be combined to give a first stage where sputtering predominates, followed by a second, mainly sputter-etching, stage. In this way, the surface of the SiO 2  film is made planar by the time the film has achieved the required thickness. The sputter-etching can be accomplished by RF sputtering apparatus. The raised portion of the SiO 2  film may be partially chemically etched, prior to sputter-etching, with an aqueous solution of NH 4  Cl and HF.

Title: Shaft bearing assemblies
IPC: F16C33/76
Filed: 1972-11-24
Abstract: 1421540 Seals; bearings ROLLS-ROYCE (1971) Ltd 23 Nov 1973 [24 Nov 1972] 54476/72 Headings F2A and F2B A shaft bearing assembly, particularly for the fan shaft of a gas turbine, comprises inner and outer bearing races and a first seal having components movable with each race to form a seal across the bearing, one of the races being capable of displacement transversely of the shaft axis and having a seal element secured relative to it and co-operating with a further seal element on the shaft or housing to which it is relatively fixed, the second seal so formed being capable of accommodating the transverse movement so as to preserve sealing. The device permits inversion of a fan shaft running above critical speed in the event that it is unbalanced by loss of blades on being subject to other heavy radial loads. An arrangement in a gas turbine having a port fan 10 on a shaft 11 comprises a race 24 of a thrust bearing 21 which is secured to the shaft and an outer race 25 secured to the housing. Seals.-Seal elements 30, 31, 58, 59 secured relative to the shaft and housing respectively, form two labyrinth seals in series across the bearing. The race 25 is supported radially by a vibration damping hydrodynamic squeeze film in a space 42 between the race and a frangible annulus 43 as described in Specification 1,418,907. Under radial load, the annulus may shear at necks 44, 45, a second squeeze film in a space 46 between the annulus and housing damps bearing movement, permitting the race 25 moving radially the sum of the radial clearances of the two squeeze film spaces 42, 46. The seal elements 58, 59 are formed on a ring 39 which is attached to the race 25 and this ring also carries piston-type rings 65 in grooves 66, or 0-rings, Fig. 3 (not shown), which co-operate with rings 63, 64 secured to the housing to form a pair of the secondary seals. Interengaging dog elements 55, 56, 61, 62 prevent movement between the race 25 and the ring 39 and the housing, while splines 33 on the shaft positively drive the labyrinth seal elements 30, 31. Pressurized air may be fed to the seals through passages 70, 71 to prevent escape of lubricant from the bearing. In an alternative arrangement, the seals would be lip seals (not shown). Lubrication.-A reservoir of oil is retained in an annular space 35 about the shaft 11 and is caused by centrifugal force to flow through passages 36, 37 to the bearing. Oil leaving the bearing passes through parts 38 in the ring 39 into a space 40 and from thence by passages 41 to the space 42 to form the squeeze film mentioned earlier. Spring means in lieu of a squeeze film may resist the radial movement.
